League of Legends Patch 13.1B Revealed: ADC Buffs, Yuumi Hit with Ban Hammer

League of Legends’ second patch of Season 13 is all set to bring forth massive changes via multiple nerfs, crit changes, and much-needed buffs for the attack damage carries (ADCs) in the game. Notably, the second patch was supposed to get released on 25th January but according to Riot Games, it has been delayed due to an unexpected social engineering attack. As a result, it has been broken down into a hotfix micropatch in League of Legends (LoL) Patch 13.1B. 

Riot Games introduced LoL Patch 13.1B and wrote, “With that said, we’re one patch into the year and following up Preseason with some sweeping changes to marksmen, their items, and fighter items. We also have a few pro-skewed nerfs to address the likes of Lucian/Nami and Yuumi, Chemtech Drake buffs, new Lunar Gods skins, and an update to surrender voting. See you on the Rift!”

We are also getting a handful of new Lunar Year skins in this patch. Riot Games revealed that Lunar Emperor Thresh, Lunar Empress Ashe, Lunar Empress Qiyana, Lunar Guardian Kha'Zix, Lunar Guardian Malphite, and Prestige Porcelain Lissandra will be available on 26th January. Here’s everything you need to know about LoL Patch 13.1B.

ADC Class Adjustments - Crit changes

One of the headlining changes in the micropatch is that Riot Games is adjusting Infinity Edge and Navori Quickblades to make them available as second items so that ADCs can access their most important power spike earlier in the game. Additionally, it is also buffing Bloodthirster and has done away with some of the late-game mana constraints that several ADCs face.

Grievous Wounds Changes in LoL Patch 13.1B

Players should note that Riot Games is buffing Grievous Wounds items, but not Grievous Wounds itself. The company wants players to make Grievous Wounds accessible and also make sure that it makes sense in builds with good gold efficiency. It added, “We don't want you playing minigames to access Grievous Wounds - we want it to just work when you need it.” Notably, it has not increased the Grievous Wounds amount from 40% back to 60%. 

Riot has buffed the following Grievous Wounds items:
